But yes. Having spent an unhealthy amount of time staring mindlessly onto the floors of airplanes, there's essentially track runners that the seats clip into. There's spaces for seats every inch or so to provide flexibility by the operating carrier. This seems to be a pretty universal solution on just about every variation of every plane, irregardless of manufacturer or operating carrier.

In my simple mind it's as simple as pulling the seats up, and moving them to the desired position. Of course I'm sure there's all sorts of regulatory that is required before you can do that, but the actual act of doing it doesn't seem all that difficult.
